Dental Loupes With Integrated Blacklight Lens for Composite Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dental professionals face difficulties in accurately identifying previously repaired teeth due to composite bonding, which complicates charting and treatment, and existing solutions like blacklights are not commonly used due to contamination risks and inefficiencies, while x-ray imaging is costly and time-consuming.
Innovation Solution
Dental loupes equipped with a light source, composite lens, and blacklight lens that allow interchangeable use, enabling the emission of visible light for curing and ultraviolet light to highlight composite fillings, with magnetic and pivoting mechanisms for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If a blacklight is used to highlight composite fillings, then the ability to identify repaired teeth is improved, but the risk of contamination increases and work efficiency decreases due to hand-held operation
Solution Approach 1:
The patent combines the blacklight function with the dental loupe system by integrating a light source and blacklight lens into the loupe structure. This merging allows the blacklight to be used without requiring separate hand-held operation, eliminating contamination risk while maintaining the ability to identify repaired teeth through fluorescence highlighting.
Solution Approach 2:
The dental loupe system is designed with multi-functionality, incorporating both standard lighting and blacklight capabilities through interchangeable lenses. This universal design allows the same device to serve multiple purposes: general examination, composite identification, and curing guidance, thereby eliminating the need for separate hand-held blacklights that pose contamination risks.
2Difficulty of detecting and measuring
If a blacklight is used to highlight composite fillings, then the ability to identify repaired teeth is improved, but work efficiency decreases due to hand crowding the treatment area
Solution Approach 1:
By merging the blacklight function into the integrated loupe system, the patent eliminates the need for separate hand-held blacklight operation. The blacklight lens is built into the loupe structure, allowing illumination without hand interference in the treatment area, thus improving work efficiency while maintaining composite identification capability.
3Difficulty of detecting and measuring
If x-ray imaging is used to highlight composite portions, then the ability to identify repaired teeth is improved, but cost and time consumption increase
Solution Approach 1:
The patent utilizes fluorescence color changes to identify composite fillings. The blacklight lens converts ultraviolet light into visible fluorescence that causes composite materials to glow, providing immediate visual identification without requiring time-consuming x-ray imaging processes. This optical method is both faster and more cost-effective while maintaining accurate detection capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables fast, sterile, and efficient identification of composite fillings and assessment of dental integrity without hand-held contamination risks, allowing hands-free operation and clear differentiation between repaired teeth and natural enamel.
Implementation Method 1
the blacklight lens filters out visible light and emits ultraviolet light that causes composite within a patient's mouth to fluoresce
Data Source
AI summary
Dental loupes feature a light source, a composite lens, and a blacklight lens. Each lens may be hingedly coupled to the light source to prevent composite from curing or cause composite to fluoresce. The dental loupes have magnets for securing the position of each lens and/or may have a formfactor configured to allow ease of rotation and positioning. In some examples, the dental loupes include a first bracket coupled to and rotatable about a second bracket via a pin. The first bracket has a first aperture configured to hold a light source. The second bracket has a second aperture configured to hold a composite lens and a third aperture configured to hold a blacklight lens. In a first configuration, the light source aligns with the composite lens, preventing curing of composite. In a second configuration, the light source aligns with the blacklight lens, causing composite to fluoresce.
